... energy has much too low a frequency to be absorbed in the normal way by water. Water has two characteristics which apply in this case: (1) The water molecule (H2O) is an electric dipole the way a bar magnet is a magnetic dipole. The oxygen end has a greater affinity for electrons than the hydrogen e ...

Energy Exists in Many Forms
... Energy may be transformed between different forms at various efficiencies. Items that transform between these forms are called Transducers. It's good to know that energy does not disappear, it merely changes form. To receive different forms of energy we use different energy sources and technologies. ...
